摘要/Abstract

摘要： 由于具有低成本、高性能等优点,目前钙钛矿太阳能电池被广泛关注。此外,SnO₂具有禁带宽度适中、载流子迁移率高、减反射性能优异等优点,因此被广泛用作电子传输层。本工作主要分析电子传输层厚度、空穴传输层厚度、钙钛矿吸收层厚度、环境温度、串联电阻以及并联电阻对器件性能的影响。研究结果表明,最优的SnO₂电子传输层厚度为40 nm,最优的Spiro-OMeTAD空穴传输层厚度为70 nm。随着钙钛矿吸收层厚度增加,太阳能电池的光电转化效率不断提高,当钙钛矿吸收层厚度达到650 nm时光电转化效率达到饱和。此外,环境温度的上升导致填充因子以及短路电流的下降,从而使得器件性能退化。太阳能电池的寄生串联电阻和并联电阻分别会导致短路电流和开路电压下降。最后,我们的仿真结果表明,FTO/SnO₂/CH₃NH₃PbI₃/Spiro-OMeTAD/Ag结构的钙钛矿太阳能电池可以耐受高达10¹³ cm^-2的质子束辐照。本研究为发展高性能钙钛矿太阳能电池及其空间应用提供了重要的理论指导。

Abstract: The perovskite solar cells attracted great attention owing to their low cost and high performance. SnO₂ as electron transport layer has been mostly used in the perovskite solar cells due to its excellent properties, such as good anti-reflection, suitable band gap, and high electron mobility. In this study, electron transport layer thickness, hole transport layer thickness, perovskite layer thickness, temperature, shunt resistance, and series resistance are investigated on the performance of perovskite solar cells. According to the results, the optimal thickness of SnO₂ layer, Spiro-OMeTAD layer, and perovskite layer are 40 nm, 70 nm, and 650 nm respectively. In addition, with the environment temperature increasing, fill factor and short circuit current density keep decreasing. Moreover, shunt resistance and series resistance will deteriorate open circuit voltage and short circuit current density respectively. Finally, the proton irradiation resistance of FTO/SnO₂/CH₃NH₃PbI₃/Spiro-OMeTAD/Ag can reach up to 10¹³ cm^-2. This work will provide guidance to develop high performance perovskite solar cells and the application in space environment.
